Role overview

Wealthsimple, Canada’s leading financial innovator serving over 4 million Canadians with $169 billion in assets under administration, is building a new business lending program for small and medium-sized businesses. You will join the Credit Analytics team as a Senior Associate to own credit policy for this green-field initiative, starting with a business credit card product and working across the entire account lifecycle from underwriting through risk management.

Key responsibilities

Design and implement the adjudication policy for the business credit card, including entity-level underwriting criteria, principal and guarantor assessment, initial limit-setting, and approval decisioning.
Own line management strategy for business credit products, overseeing credit limit increases and decreases, pricing, authorization rules, and active exposure management based on cash-flow and balance monitoring.
Partner with the collections team to design risk-managed treatment strategies for business accounts and build lifecycle monitoring systems that identify emerging risk early.
Evaluate portfolio performance through vintage analysis, cohort tracking, and champion/challenger testing to validate and refine underwriting decisions.
Develop policy enhancements that improve profitability while maintaining risk appetite, grounded in rigorous root-cause analysis.
Define the data and underwriting infrastructure for small business lending, including sourcing, validating, and weighing business financial data alongside traditional bureau signals.
Collaborate cross-functionally with Engineering, Product, Data Science, Fraud, and Client Experience teams to translate policy into automated adjudication and monitoring systems.

Requirements

Direct experience underwriting or setting credit policy for small and medium-sized businesses is essential for this role.
Hands-on ability to write SQL to self-serve data and build monitoring and analytics.
Demonstrated ability to shape policy in a ship-and-iterate environment while product definition is still evolving, balanced with credit discipline.
Strong analytical and communication skills to translate analysis into clear recommendations for both technical and non-technical audiences.
Intellectual curiosity, passion for the work, and desire for ownership over projects.
At least 5 years of experience in small business lending preferred.
Familiarity with Canadian consumer credit bureau data (Equifax, TransUnion) and understanding of how business credit risk differs from consumer credit risk.

What makes this role worth considering

You will have the rare opportunity to build a new lending program from the ground up with visibility into every component, from policy design through funding, and genuine runway to grow into leading an entire lending line of business. The Credit Analytics team operates at the intersection of high-growth fintech and data-driven underwriting, challenging traditional credit assessment models to build inclusive products for millions of Canadians and their businesses.
